Abstract: This Ph.D. thesis is concerned with the role of the business intelligence (BI) output in organizational decision-making processes. The primary focus of this thesis is to investigate how this BI output is employed and deployed by decision-makers to shape collective judgement and to reach organizational decisions. Concerning the role of the BI output in decision-making the BI literature is characterized by normative ideas of how the BI output should be used in decision-making and how it can enable people to make better decisions. Most previous work has concerned methods and technologies to collect, store and analyze BI. It has also, assumed a rational approach to decision making where data from information systems are used to inform decisions either by reducing uncertainty, ambiguity or complexity. This study attempts to establish knowledge about the role of the BI output in the IT project prioritization process of the Group IT of the Danske Bank Group. Hence, the starting point of this thesis is a 16-month long interpretive study from March 2010 till July 2011 during which I observed the prioritization process and collected various forms of data. I use a rich dataset built from this longitudinal study of the IT project prioritization process in Group IT where thematic analysis is used to analyze the data. Overall, the study operates under the interpretive paradigm, which assumes that the world and knowledge are socially constructed. URI: http://hdl.handle.net/10398/8664 Files in this item: 1

Designing Sensor-based Predictive Information Systems for Forecasting Spare Part Demand for Diesel EnginesFurtak, Szymon (Frederiksberg, 2018)[More information][Less information]
Abstract: As digital technologies become prevalent and embedded in the environment, "smart" everyday objects like smart phones and smart homes have become part and parcel of the human enterprise. The ubiquity of smart objects, that produce ever-growing streams of data, presents both challenges and opportunities. In this dissertation, I argue that information systems extending these data streams, referred to as "predictive information systems with sensors", can generate added value and will be gaining momentum in academia and in the industry. Subsequently, seeing apparent complexity in designing IS artifacts with such functionality, I introduce a framework for Designing Information Systems with Predictive Analytics (DISPA), extending Design Science Research specifically towards rigorous design of predictive analytics. The framework is evaluated based on a case study of MAN Diesel and Turbo, a lead designer of marine diesel engines generating multiple applicable artifacts in the process. Additionally, the framework exemplification in the case context led to supplementing the framework with a set of Design Principles for Designing Predictive Information Systems as well as a matrix for pre-assessing financial feasibility of predictive information systems with sensor technologies. This work provides a contribution to information systems research, and in particular to design science research, by introducing a model for Designing Information Systems with Predictive Analytics (DISPA) that can serve as a method for developing IS artifacts. The framework constitutes an Information System Design Theory consistent with the established definitions from the literature (Gregor & Jones, 2007; Kuechler & Vaishnavi, 2012; Walls, Widmeyer, & El Sawy, 1992). In addition, the paper introduces and systematically evaluates a number of spare-part forecasting methods, which can be considered a contribution to operations research literature.

Lasrado, Lester Allan (Frederiksberg, 2018)[More information][Less information]
Abstract: Despite being widely accepted and applied, maturity models in Information Systems (IS) have been criticized for the lack of theoretical grounding, methodological rigor, empirical validations, and ignorance of multiple and non-linear paths to maturity. This PhD thesis focuses on addressing these criticisms by incorporating recent developments in configuration theory, in particular application of set-theoretic approaches. The aim is to show the potential of employing a set-theoretic approach for maturity model research and empirically demonstrating equifinal paths to maturity. Specifically, this thesis employs Necessary Condition Analysis (NCA) to identify maturity stage boundaries as necessary conditions and Qualitative Comparative Analysis (QCA) to arrive at multiple configurations that can be equally effective in progressing to higher maturity. Furthermore, this thesis prescribes methodological guidelines consisting of detailed procedures to systematically apply set theoretic approaches for maturity model research and provides demonstrations of it application on three datasets. The thesis is a collection of six research papers that are written in a sequential manner. The first paper reviews literature on maturity models in IS, identifies research gaps and proposes use of configurational theory to address these challenges. The second paper conceptualizes stage boundaries as necessary conditions and demonstrates the application of Necessary Condition Analysis (NCA) on a social media maturity dataset. Building on the second paper, the third paper conceptualises maturity stage characteristics in terms of configurations using Qualitative Comparative Analysis (QCA). Overall, the third demonstrates empirically the existence of multiple paths to maturity and provides IS researchers with a six-step procedure and detailed guidelines to systematically apply set theroretic approaches to maturity models (STAMM). The fourth paper then uses the social media maturity dataset, computes maturity scores using different quantitative methods prescribed in maturity models literature and proposes recommendations for maturity model designers. The fifth and sixth papers are demonstrations of applicability of STAMM on different datasets. The fifth replicates and extends a prior research study on ITIL maturity and compares the findings with the results using STAMM. Finally, the sixth paper argues for a multi-method approach by combining STAMM and PLS-SEM in understanding the conditions associated with IT service management (ITSM) maturity. This PhD thesis contributes to the academic discussion on how maturity occurs through configurations. The key contribution is STAMM, a set-theoretic procedure model and method, which employs FsQCA and NCA to empirically demonstrate multiple paths to maturity (or equifinality). It also contributes to set-theoretic approaches, in particular QCA and NCA. Finally, this thesis contributes to multimethod approach by harmoniously integrating PLS-SEM, QCA and NCA, thus adding to the limited body of multi-method literature.

An Information Infrastructure to Improve International Containerized ShippingJensen, Thomas (Frederiksberg, 2017)[More information][Less information]
Abstract: This thesis applies theoretical perspectives from the Information Systems (IS) research field to propose how Information Technology (IT) can improve containerized shipping. This question is addressed by developing a set of design principles for an information infrastructure for sharing shipping information named the Shipping Information Pipeline (SIP). Review of the literature revealed that IS research prescribed a set of meta-design principles, including digitalization and digital collaboration by implementation of Inter-Organizational Systems based on Electronic Data Interchange (EDI) messages, while contemporary research proposes Information Infrastructures (II) as a new IT artifact to be researched. Correspondingly, this thesis applies the concept of and design theory for II to improve containerized shipping. Activity Theory has guided the analysis of containerized shipping, following avocados on their journey from the trees in Africa, to the retail shelves in Europe, revealing the plethora of organizations, activities and documents involved. The implication being that containerized shipping becomes inefficiently; costly, unreliably, and risky. These are posited as the major impediments to creating a more efficient shipping industry, and a number of critical issues are identified. These include that shipments depend on shipping information, that shipments often are delayed due to issues with documentation, that EDI messages account for only a minor part of the needed information, that multiple fragmented II are used throughout, and finally, that there is an unleashed potential for IT to support containerized shipping. Based on the above, the SIP was designed, prototyped and evaluated which, through Internetenabled collaboration on shipments, ameliorates the previously mentioned critical issues and major impediments. This is accomplished primarily through increased transparency into the containerized shipping process and through providing direct access to source information about the shipments. Based on the prototypes an accumulated set of design principles for the design of SIP are articulated. In the particular context of Internet-enabled II utilizing the World Wide Web, an extension of design theory is proposed through the formulation of an additional metadesign principle: share meta-information only and govern access to detailed information by the source. Finally, the practical implications of SIP are estimated, including how it facilitates more efficient containerized shipping and in turn sustainable international trade. The positive acknowledgements of SIP prototypes support how II designed in accordance with the developed set of design principles can be used to significantly improve containerized shipping.

Design, Development and Evaluation of a Visual Analytics Tool for Computational Set Analysis of Big Social DataFlesch, Benjamin Johannes (Frederiksberg, 2019)[More information][Less information]
Abstract: This dissertation presents the design, development and evaluation of the Social Set Visualizer, an innovative Visual Analytics software tool, that expands upon a novel set-based approach to Big Social Data Analytics for large-scale datasets from social media platforms such as Facebook. Over the course of five peer-reviewed publications, three different versions of the Visual Analytics software tool are iteratively designed and developed, and several contributions to the visualization of sets and set intersections are highlighted. In seven case studies with the Social Set Visualizer software tool the generation of meaningful facts and actionable insights from Big Social Data are empirically demonstrated, and a pre-existing research gap with regard to the Visual Analytics of large-scale Facebook datasets vs. other social media platforms is closed. Based on these studies, the dissertation puts forward a generalized conceptual model for interactions within Big Social Data termed the Social Interaction Model, which provides a simplification and extension of previous theoretical and formal models.

Uncovering the Generative Mechanisms of Open Data through a Mixed Methods ApproachJetzek, Thorhildur Hansdottir (Frederiksberg, 2015)[More information][Less information]
Abstract: The impact of the digital revolution on our societies can be compared to the ripples caused by a stone thrown in water: spreading outwards and affecting a larger and larger part of our lives with every year that passes. One of the many effects of this revolution is the emergence of an already unprecedented amount of digital data that is accumulating exponentially. Moreover, a central affordance of digitization is the ability to distribute, share and collaborate, and we have thus seen an “open theme” gaining currency in recent years. These trends are reflected in the explosion of Open Data Initiatives (ODIs) around the world. However, while hundreds of national and local governments have established open data portals, there is a general feeling that these ODIs have not yet lived up to their true potential. This feeling is not without good reason; the recent Open Data Barometer report highlights that strong evidence on the impacts of open government data is almost universally lacking (Davies, 2013). This lack of evidence is disconcerting for government organizations that have already expended money on opening data, and might even result in the termination of some ODIs. This lack of evidence also raises some relevant questions regarding the nature of value generation in the context of free data and sharing of information over networks. Do we have the right methods, the right intellectual tools, to understand and reflect the value that is generated in such ecosystems? URI: http://hdl.handle.net/10398/9183 Files in this item: 1

Abstract: Digital platforms are layered modular information technology architectures that support disruption. Digital platforms are particularly disruptive, as they facilitate the quick release of digital innovations that may replace established innovations. Yet, despite their support for disruption, we have not fully understood how such digital platforms can be strategically designed and configured to facilitate disruption. To that end, this thesis endeavors to unravel disruptive digital platforms from the supply perspective that are grounded on strategic digital platform design elements. I suggest that digital platforms leverage on three strategic design elements (i.e., business, architecture, and technology design) to create supportive conditions for facilitating disruption. To shed light on disruptive digital platforms, I opted for payment platforms as my empirical context and unit of analysis. Through primary and secondary data sources, findings suggest that digital platforms with an Analyzer and Prospector strategy profile have favorable conditions to facilitate disruption. It is envisioned that insights gleaned from multiple cases will contribute towards bridging existing knowledge gaps in strategic management, digital platforms, and open innovation literature.

From Vendors to CustomersRiis, Philip Holst (Frederiksberg, 2012)[More information][Less information]
Abstract: Enterprise Systems (ES) are generally considered the price of entry for running a business. With the increased scope of ESs to encompass nearly every function or business process of a modern organization, an increasing number of different users are adopting and using the systems. These users occupy a number of different organizational roles which include a wide variety of different tasks in organizations and have very different requirements for ESs. To ensure a better fit between users and ESs, a number of ES vendors have begun to focus on reflecting the concept of organizational roles of users in their systems. Limited research has, however, addressed these “role-oriented” ESs; this dissertation attempts to provide a better understanding of them by studying their design, implementation, and use. The research design for this dissertation is based on Case Studies and the Grounded Theory Method with qualitative empirical data collected across three types of actors in an ES ecosystem: Vendors; partner companies; and customers. The findings are primarily presented in six appended research papers that are aimed at both researchers and practitioners. The main contribution of the dissertation is an improved understanding of: Representation of organizational roles in the deep and surface structures of ESs; the mapping, configuration, and tailoring of predefined systems roles to fit actual roles of users in organizations; and the potential benefits and role-related misfits of role-oriented ESs. Through discussion of the findings, the dissertation also illustrates how the design of role-oriented ESs is influenced by the different actors in an ecosystem. The dissertation also illustrates how systems, organizations, processes, and roles can be aligned during implementation by shifting basis and conceptual focus in the requirements analysis. Finally, the dissertation explains the impact of roleoriented technology on organizational performance and how this technology may influence the existing perception of the role taking process in organizations.

A cross-cultural study of the relation between users´ cognitive style, context of use, and information architecture of local websitesNawaz, Ather (Frederiksberg, 2013)[More information][Less information]
Abstract: Increasing globalization and technological development has led companies and people across the globe to connect through the global internet community. However, people with different cultural backgrounds may perceive the same information in different ways. One of the hurdles to use websites efficiently is the indifferent structures of information on website, and their relation with the characteristics of intended users and the context of use for the websites. The purpose of this dissertation is to assist HumanNComputer Interaction (HCI) practitioners and researchers with better design of website structures for user groups with different cultural backgrounds. This dissertation looks into issues related to website user experience (UX) and focus on how the structuring of information is seen from local users’ perspectives. In particular, it attempts to look into the alignment between websites’ information architecture (IA) and users’ views of website information structure, by applying a crossNcultural and context of use perspective on the UX of websites in three countries: Pakistan, Malaysia, and Denmark. The researcher investigates to what degree users’ cognitive styles and contexts of use are aligned with local websites’ information architecture, and how this (lack of) alignment shapes the resulting UX.
